Problem: Two long parallel wires each carry 2.6A in the same direction, with their centers 1.1cm apart.
Part A: Find the magnitude of the magnetic field halfway between the wires.
Part B: Find the magnitude of the magnetic field at a point in the same plane as the wires, 1.1cm from one wire and 2.2cm from the other.
Part C: Find the magnitude of the force of interaction (per lenght) between the wires.
I need help to find the magnitude of the magnetic field halfway between the wires.
